It's a bit late now as I've already purchased and getting ready to install the only ones I could find for the 2007-2009, C2P20052, which also happen to be about the most expensive. One would think they were limited and exclusive to the first gen X150 as I could find no other equivalent anywhere. However after receiving them I did a quick search of the WERS number on the label 6W83-6A003-AE and found pictures of XF, XJ, XK mounts which look identical as well as several other Jaguar part numbers such as C2P17845, C2D2745 and C2Z5066 which reference pictures of mounts which appear identical to the ones I purchased, but for a lower cost as well as low cost aftermarket options. As I said the labels and pictures appear identical between the X150 exclusive and the other part numbers and models. It is not unusual for Jaguar to share parts from model to model, in fact it's quite common, however part numbers typically are also the same.

So, does anyone know if in fact there are other Jaguar part numbers and mounts which are interchangeable despite being identified as not interchangeable in parts catalogues or is there a subtle difference between them which makes them not interchangeable?

 

I'd love to find alternates for motor mounts on the XK. I'm sure it would be welcomed by a lot of owners who don't want to pay $250 each for them.

But if you figure they're trying to mount any 4.2 engine into any lower frame, it would make sense to use a similar/same part throughout. So, what cars in the 06-09 had 4.2 engines?

From wikipedia on the 4.2 NA:

• 2003–2006 Jaguar XK-series 294 hp (219 kW; 298 PS), 303 lb⋅ft (411 N⋅m)
• 2006–2008 Jaguar XK-series 300 hp (224 kW; 304 PS), 310 lb⋅ft (420 N⋅m)
• 2002–2008 Jaguar S-Type 4.2, 300 hp (224 kW; 304 PS) and 310 lb⋅ft (420 N⋅m)
• 2004–2009 Jaguar XJ8, 300 hp (224 kW; 304 PS) and 310 lb⋅ft (420 N⋅m)
• 2008–2010 Jaguar XF, 300 hp (224 kW; 304 PS) and 310 lb⋅ft (420 N⋅m)

This one from Alibaba looks very similar. Of course, chinese no name is always a crapshoot.

I paid I think $88 for mine, and it was tagged as a Jaguar part. Hellifino where I bought them from though. Maybe Amazon? Rock Auto???

 

What mileage were they when you changed them? And how long have they been on?

 

lincoln ls 3.9.

you can get aftermarkets starting at like $12

 

Uh, I think it was two years I changed the one because the rotation tore the intake elbow. So, nine years and about 68,000 miles. Course, I drive like an idiot with an ON-OFF throttle. That's kind of hard on engine mounts.

 

Thanks. Just trying to figure lifespan. I replaced them at 90K on my BMW and it made a noticeable difference in quiet. With an 80K XK I'm wondering if they're near EoL. But $250 each is too much to just toss them in for ***** and grins.

 

About 60K miles on mine, of course the last several thousand miles have been road course miles with aggressive acceleration, deceleration/braking.

For curiosity would still like to know the answer to my original question. I reckon I could buy one of the others used on eBay or the like and compare to mine.

Yes but I’ve a 2008 which per Jaguar only has 1 compatible part number which is exclusive to the 2007-2009 MYs. When I received that specific part from Jaguar, I searched the WERS number which then lead me to engine mounts from other models and years. Pictures also indicate the look the same. The questions why would Jaguar create separate non-interchangeable part numbers based on year and model of there wasn’t a difference of some sort.

However WERS numbers are off a different system, which as far as I understand are specific to a part regardless of Jaguar catalogue numbers. For example I’ve used WERS numbers to find equivalent parts elsewhere such as Ford control arms compatible with Jaguar, etc.

 

Does WERS only apply to Ford, or is it otherwise a universal designation?

 

It’s Ford’s world wide engineering parts system, I reckon because at one time Ford owned Volvo, Aston Martin, Land Rover, Jaguar, Mazda etc and many parts were shared, they’d have make exclusive numbers for the same part identified by WERS. Interesting thing there could be vast differences in pricing from marque to marque for the same part.

 

Thanks. Was able to find lower cost alternatives to the JLR PN by using the WERS number. For an AFS controller, made by Hella, the new JLR part was $225, and the WERS part number, used, was $30.

So even if the part doesn't solve my problem, it's been a cheap test. Note that I only buy used parts when safety isn't involved.

 

I usually have some success by checking Rock Auto for cross-matching part numbers. A lot of times, the parts will say what other models (even across manufacturers) the parts will fit.

And, I feel your pain regarding the engine mounts. I'm in the process of replacing the mounts I just removed from my '11 XFR, but I'm trying not going with OEM this time. I'm working with a racing machine shop to modify some existing aftermarket mounts they make for Corvettes to fit my XFR without any modifications to my brackets, etc. That's a whole other story, though. If they work out, I'll start a thread on them.

Also, not sure if it helps, but these are the OEM mounts I just pulled off of my car. Let me know if you need additional pix or measurements from my car's OEM mounts, as the they're still sitting on my workbench.

Jaguar insists this part number's unique to the first generation X150 ut as you can see it looks just like the other part numbers...

 

@xalty - Yep - I've seen it. If you'll look at the last post, I asked how they worked out. I assume the OP is no longer involved with the forum, as I didn't get a response.

 

If the mounts are truly the same despite Jaguar's catalogue, then there are less costly alternatives. I had seen that Hinson post some time ago when I was considering solid mounts. I've actually considering using solid mounts on the entire drive train (engine, trans, drive line, etc.) but could find no conclusive evidence of the benefits AND I did see where if something fails, rubber mounts are sacrificial where as with solid mounts should something go wrong, severe damage to the drive train could occur.

 

Looking at the X250 mounts:

https://www.ebay.co.uk/itm/284179461...Cclp%3A2047675

Look similar, and quite a few out there at a reasonable price. Any knowledge on fit?

 

the gas engine mounts are the same design since the 1999 s-type and lincoln ls.

it never changed until the 3.0/5.0 mount which has one part number for all the dew98 cars, x150 x250 x351 and f-type
